Para proporcionar a las plantas en la agricultura el nitrógeno requerido por ellas, se emplean esencialmente compuestos de amonio como fertilizantes. To provide plants in agriculture with the nitrogen required by them, essentially ammonium compounds are used as fertilizers.
Los compuestos de amonio se transforman en el suelo en un tiempo relativamente corto microbialmente en nitrato (nitrificación). Sin embargo, el nitrato se puede eliminar por lavado desde el suelo y de esta manera puede llegar al agua subterránea. La porción eliminada por lavado no está ya disponible en este caso para la nutrición de las plantas, de manera que por este motivo no es deseable una nitrificación rápida. Por lo tanto, para el aprovechamiento mejorado del fertilizante se añaden al fertilizante inhibidores de la nitrificación. Un grupo conocido de inhibidores de la nitrificación son, por ejemplo, pirazoles. The ammonium compounds are transformed into the soil in a relatively short time microbially into nitrate (nitrification). However, nitrate can be removed by washing from the ground and in this way it can reach groundwater. The portion removed by washing is no longer available in this case for plant nutrition, so that for this reason rapid nitrification is not desirable. Therefore, for the improved use of the fertilizer, nitrification inhibitors are added to the fertilizer. A known group of nitrification inhibitors are, for example, pyrazoles.
Sin embargo, los pirazoles tienen una volatilidad alta. Por lo tanto, durante el almacenamiento de preparaciones de fertilizantes que contienen pirazoles se produce una pérdida continua de sustancia activa a través de evaporación. Por consiguiente, los pirazoles deben formularse a través de medidas adecuadas en una forma no volátil. However, pyrazoles have high volatility. Therefore, during the storage of fertilizer preparations containing pyrazoles there is a continuous loss of active substance through evaporation. Therefore, pyrazoles must be formulated through appropriate measures in a non-volatile manner.

En esta publicación EP se publican también compuestos tensioactivos de la fórmula general R-Ar SO4M, en la que R representa la mayoría de las veces un grupo alquilo ramificado y M representa cationes univalentes, en general sodio.

Se conoce por el documento DE-A-196 31 764 la utilización de poliácidos inorgánicos y orgánicos para el tratamiento de fertilizantes minerales, que contienen un inhibidor de nitrificación.

Éstos se fabrican a través de gasto químico adicional a base de pirazoles de alquilo y, por lo tanto, son costosos en la fabricación frente a los pirazoles de alquilo simples y sus sales. DE-A.198 49 496 non-volatile alkyl derivatives are known.

Ensayo de almacenamiento Storage test
Los ensayos de almacenamiento se realizaron en armarios climatizados, en los que se ajustó una temperatura constante de 30 ºC y una humedad relativa del aire constante de 60 %. Storage tests were carried out in heated cabinets, in which a constant temperature of 30 ° C and a relative humidity of 60% were adjusted.
Las muestras se pesaron en bandejas de vidrio planas de 6 cm de diámetro, de manera que existían 10 g de fertilizante en un montón plano. The samples were weighed in flat 6 cm diameter glass trays, so that there were 10 g of fertilizer in a flat pile.
En los armarios de climatización se realizó a presión normal un cambio de aire 4 veces por hora. In the air conditioning cabinets a change of air was carried out at normal pressure 4 times per hour.
Además, se procuró que las velocidades locales de la circulación dentro del armario de climatización fuesen independientes del lugar, de manera que cada muestra estaba expuesta a las mismas condiciones de evaporación. In addition, it was intended that the local circulation speeds within the air conditioning cabinet be independent of the location, so that each sample was exposed to the same evaporation conditions.
En ensayos previos se pudo constatar que estas condiciones simulan muy bien la volatilidad en la superficie de montones reales. Las muestras fueron extraídas en el ejemplo al cabo de 4 semanas de almacenamiento en el armario cerrado. Se pulverizaron las muestras y se determinó en la solución de extracción con HPLC el contenido de DMP en comparación con el contenido antes del almacenamiento. También se pueden realizar tiempos de almacenamiento más cortos y más largos. In previous tests it was found that these conditions simulate very well the surface volatility of real heaps. The samples were extracted in the example after 4 weeks of storage in the closed cabinet. The samples were sprayed and the DMP content was determined in the HPLC extraction solution compared to the content before storage. You can also perform shorter and longer storage times.
Las abreviaturas indicadas en la Tabla 1 significan: The abbreviations indicated in Table 1 mean:
DMP = dimetilpirazol DMP = dimethylpyrazole
DMPP = fosfato de dimetilpirazol DMPP = dimethylpyrazole phosphate
Colada-V = ácido polinaftalinsulfónico Colada-V = polynaphthalene sulfonic acid
La Tabla siguiente muestra que el empleo de ácidos polisulfónicos proporciona una mejora clara de la estabilización. The following Table shows that the use of polysulfonic acids provides a clear improvement in stabilization.
En este caso, se alcanzó una estabilización mejorada, por ejemplo en fertilizantes de NPK (nitrógeno/ fosfato/potasio), en fertilizantes NP y en fertilizantes puros de nitrógeno, como por ejemplo urea y ASS (salitre de sulfato de amonio). In this case, improved stabilization was achieved, for example in NPK (nitrogen / phosphate / potassium) fertilizers, in NP fertilizers and in pure nitrogen fertilizers, such as urea and ASS (ammonium sulfate saltpeter).
Los fertilizantes indicados se caracterizan la mayoría de las veces por sus contenidos de sustancias nutritivas (20+8+8 significa 20 % N, 8 % P2O5, 8 % K2O). El cuarto número indica el contenido de magnesio. The indicated fertilizers are characterized most of the time by their nutrient content (20 + 8 + 8 means 20% N, 8% P2O5, 8% K2O). The fourth number indicates the magnesium content.
